Took the wife and 2 older kids (8 yr old girl, 6 yr old boy) to see Alexander and the Terrible, Horrible, No Good, Very Bad Day last night.  Last family movie I went with them to see was Earth to Echo (no link since it was such a horrible movie).  I was expecting to hate it and the kids to love it because they've never seen a bad movie.  I was pleasantly surprised and I highly recommend it for a family movie.  I would even have to say it was worth the $60 or so I spent.  Two thumbs up.
